WATER-CLOSET BOWL.

Application filed May 29, 1908.

To all whom it may concern:

Be it known that I, ANTON T. LUECKEN- EACH, a citizen of the UnitedStates, residing at Neenah, in the county of Winnebago and State ofWVisconsin, have invented a new and useful Tater-Closet Bowl, of whichthe following is a specification.

My invention relates to the manner of ventilating the bowl by arrangingthe mouth of the foul air ventilating duct at a point as high or higherthan the flushing channel around the bowl top, and the object of theimprovement is, to improve the ventilation of the bowl by having saidmouth on a level, or a little higher in some cases, than the body of airin the bowl which has been warmed by the body of the person using thebowl, and also, by the discharge therefrom, as it is a well knownprinciple in science that the cool air will, because of its greaterspecific gravity, fall below the warm air and force the latter out of aroom or other inclosed space if flues or openings are properly provided,the warm air rising and running off of the body of cool air'just asnaturally as oil will float from the surface of water.

The type of bowl shown is one that ventilates through a partition wallat the rear of the bowl, but that is not an essential element, as boththat and the flushing pipe may enter the bowl from any convenientdirection.

My invention is shown in the accompanying drawing, in which,--

Figure 1 is a side elevation of an approved form of bowl, but I make noclaim to any thing in its construction, excepting as hereafterparticularly described. Fig. 2 is a vertical section of the upper partof a bowl, longitudinally thereof. Fig. 3 is a horizontal section of thebowl upon the irregular line a, a, of Fig. 2. Fig. 4 is a transversesection of the bowl upon the irregular line Z), Z), of Fig. 2, thehinges for the seat and its cover standing upward. Fig. 5 is anelevation showing the outer ends of the ventilating duct and flushinginlet in Figs. 1 and 2. Fig. 6 is a vertical section of the upper partofa bowl longitudinally thereof, and showing a modification in thearrangement of the ventilating duct and flushing inlet, from the oneshown in Fig. 2. Fig. 7 is a plan partly in section horizontally, of theright hand end of part of Fig. 6 that is below the line 0, 0, of saidfigure. Fig. 8 is a plan of the lower side of the seat of the bowl, atits rear end. Fig. 9 is a vertical Specification of Letters Patent.

section, similar to the right hand end of Fig. 6, showing a metallicwater flushing pipe instead of an earthenware one as in Fig. 6.

Similar numerals indicate like parts, with letters, in the severalviews.

1, indicates the body 01" a bowl which may be of the siphon jet type asin Fig. 1, or a wash down variety, the particular construct-ion of thelower part of the bowl being immaterial.

2, indicates the upper rim of the bowl; 3, the seat having cushioningplugs 3 4, the seat cover; 5 and 6, hinge leaves by which the seat andcover are respectively hinged by the hinge post 7, to the bowl top in ausual manner.

The inlet for the flushing water may be arranged as in Figs. 1 and 2, toenter the bowl from the rear in a nearly horizontal direction, as 8, oras 8, from above, as in Fig. 6, it passing through the ventilating ductas shown in said figure and in Fig. 7.

The mouth 9, of the ventilating duct 10, is arranged to enter the bowlat the rear of the seat, the seat being hinged so as to form when closeddown, a close joint with the mouth 9, said mouth 9 having a curve ateach upper corner and the lower side of the seat having a rabbet 11corresponding in form with the mouth 9, a channel 11 being formed in theseat leading from said rabbet forward to the seat opening 8*, so thatthere is an unobstructed channel from the seat opening at the highestpoint above the bowl in which a body of air can accumulate, when thebowl is in use, to the mouth of the ventilating duct.

It will be observed that the plugs 3", hold the lower edge of the seatabove the bowl top and provide a space between the seat around the bowltop excepting at the mouth 9 of the duct 10, for the admission ofoutside air, which will be drawn into the bowl when a person is upon theseat, by reason of the air next to the body of the person being warmerthan it is outside of the bowl. This inward rush of air assists thedraft from the body of air under the seat, into the ventilating duct andkeeps a continuous current of air from the outside, passing into and outof the bowl into the ventilating duct, and consequently, takes away theodors as long as the seat is occupied. The seat is concaved at 3, aroundthe opening 3 for the purpose of providing a channel next to the body ofthe occupant vided by the channel 11.

In Fig. 2, the Water inlet pipe 8, conducts the flushing current to thesiphon jet aperture 12 and to the channel 13, around the rim of thebowl, and in Fig. 6, the inlet 8*, supplies the channel 13, and theventilating duct 10*, passes around the inlet pipe 8, its

mouth being in the same position relative to the bowl top as in Figs. 1and 2.

In Fig. 9, a modification in the flushing pipe is shown, in forming thepipe of metal instead of the same material of which the bowl is formed.Its advantage will be the taking of less room in its passage through theventilating duct, and it may consist of the pipe 8 having a collar 14:fixed to it and the ventilating pipe 10 being provided with seats 15 and16, said metallic pipe passing through the seats and being supported inone of the seats by the collar 14, a suitable cement or packing materialbeing placed in said seats around the pipe for forming anair tight jointaround the pipe. Other suitable joints well known to the mechanic may beused if desired.

1'7, indicates partitions through which the ventilating pipe passes and18, the front edge of the lower wall of the ventilating duct.

It will be evident that the lower part of the mouth of theventilating-duct may be below the bowl top and still be above the upperpart of the outlet of the flushing pipe and entrance to the flushingchannel, as the thickness of the material of the bowl top around thebowl of a half inch, more or less,

' must necessarily intervene between the flushing channel and bowl top,while the space leading from under the seat to the ventilating duct maydrop below the bowl top the thickness of said intervening bowl topmaterial, so that the entire channel leading from under the seat intothe mouth of the ventilating duct may not be entirely above the bowltop, but still be above the entrance to the flushingchannel, which isthe end in view, but the fact remains that the higher the mouth of theventilating duct is, above the inlet of the flushing channel around thebowl, the better will the ventilation of the Having described myinvention, What I claim and desire to secure by Letters Patent,- 1s:-
